Impact test machinebased on the principle of energy conservation for the test of the impact of the test specimens, instantaneous measurement and recording materials in the impact of the impact of the characteristics of the curve of the test machine. Divided into manual swing hammer impact testing machine, impact specimen notch broaching machine / projector, impact specimen cryogenic tank, automatic / semi-automatic impact testing machine, non metal impact test machine, common products have JB-S300/S500, JB-300B/500B, 750j impact test machine. Since about 1905 the advent of fast development, has become an indispensable material performance check project, through the replacement of the pendulum base, can realize the test of simply supported and cantilever two forms.
